Formula and Step-by-Step

cups × 145g/cup ÷ 28.3495g/oz = ounces
  1. Start with 3.31 cups of raisins
  2. 1 cup of raisins = 145g
  3. 3.31 × 145 = 479.95g
  4. Convert grams to ounces: 479.95 ÷ 28.3495 = 16.93 oz

The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.

Measuring Tip

To prevent dried fruit from sinking in batter, toss it with a tablespoon of flour before folding in. This does not affect the weight measurement.

Understanding the Units

What is a Cup?

In US cooking, a cup measures volume, not weight. One standard US cup holds 236.588 ml of liquid. Because different ingredients have different densities, a cup of one ingredient can weigh very differently from a cup of another.

What is an Ounce?

Ounces are commonly used in US recipes for cheese, meat, chocolate, and other ingredients sold by weight. Many kitchen scales offer both gram and ounce readings.

Frequently Asked Questions

About 16.93 oz, based on raisins having a density of 145g per cup. The exact amount depends on how the ingredient is measured and the specific product.
Multiply the number of cups by 145 (grams per cup for raisins), then divide by 28.3495 to convert grams to ounces. For 3.31 cups: 3.31 × 145 = 479.95g, then 479.95 ÷ 28.3495 = 16.93 oz.
For the most accurate results, weigh raisins on a kitchen scale. If measuring by volume, fill the measuring cup loosely and level off without pressing down. Whole and chopped pieces give different weights per measuring cup.
Weight-per-cup values vary because of differences in how the ingredient is measured (spooned vs scooped), grind size, moisture content, and settling during storage. Our values use standardized measurement methods from established culinary references.
Reverse the conversion: 16.93 oz × 28.3495 = 479.95g, then 479.95g ÷ 145 = 3.31 cups. Or use the Ounces to Cups converter.
